Our Professional Heating Replacement and Installation Process

A successful heating system replacement requires meticulous planning and execution. Our comprehensive, multi-step process ensures that your new furnace, heat pump, or boiler is perfectly matched to your home’s unique heating load and installed for maximum efficiency and longevity.

Load Calculation and System Sizing

The most critical step is accurately determining your home’s heating load. Our technicians perform a detailed assessment, considering factors such as square footage, insulation levels, window efficiency, and local climate data. This ensures your new system is correctly sized, preventing the energy waste and premature wear associated with improperly sized units.

Safe Removal and Site Preparation

We handle the complete and safe removal of your old heating unit, adhering to all safety and environmental regulations. The installation site is meticulously prepared, which includes inspecting and, if necessary, upgrading the existing gas lines, electrical connections, venting, and ductwork to ensure compatibility and safety for the new high-efficiency system.

Precision Installation and System Commissioning

Our certified installers perform the physical installation according to manufacturer specifications and local codes. The final step is system commissioning, where we test and calibrate the entire unit, verify all safety controls, check gas pressure (for furnaces), and ensure the thermostat is fully integrated and functioning optimally. We do not consider the job complete until your new system is operating at peak efficiency.

Client Education and Maintenance Planning

Following installation, our technician will walk you through the operation of your new system and thermostat. We also provide information on our preventative Heating Maintenance plans, which are essential for protecting your investment and ensuring your system continues to run safely and efficiently for years to come.

  • What are the key signs that my heater needs replacement instead of repair?

    The three primary indicators for replacement are: Age, if the unit is over 15 years old; Frequent Repairs, if repair costs exceed 50% of the cost of a new unit; and Safety Concerns, such as a cracked heat exchanger which poses a carbon monoxide risk. A professional Heating Inspection can provide a definitive diagnosis.

  • How long does a typical heating system replacement take?

    Most standard residential heating replacement projects, such as a furnace or heat pump swap, can be completed within one to two days. The duration depends on the complexity of the installation, such as whether ductwork modifications or electrical upgrades are required. Our team works efficiently to minimize disruption and restore your home’s warmth as quickly as possible.

  • Will a new high-efficiency heater save me money on my energy bills?

    Yes. Modern heating systems, especially high-efficiency furnaces and heat pumps, are significantly more efficient than models manufactured a decade ago. Replacing an old unit can reduce your heating energy consumption by 20% to 40%, leading to substantial long-term savings on your utility bills.

  • What is the importance of proper system sizing during replacement?

    Proper system sizing is crucial for both comfort and efficiency. An oversized unit will “short-cycle,” turning on and off too frequently, which wastes energy and can lead to inconsistent temperatures. An undersized unit will run constantly and struggle to heat your home adequately. Accurate sizing ensures consistent temperatures and optimal energy use.

  • Does the replacement process include removal of the old unit?

    Yes. Our comprehensive heater replacement service includes the complete and safe removal and disposal of your old unit, including the recovery of any refrigerants (for heat pumps) and adherence to all local environmental regulations. We ensure a clean worksite and a seamless transition to your new system. We also offer fast Heating Repair if a full replacement is not yet necessary.
